* 85xx: Fix enabling of L1 cache parity on secondary coresKumar Gala2010-03-30-13/+63
| | | | | | | | | | | Use the same code between primary and secondary cores to init the L1 cache. We were not enabling cache parity on the secondary cores. Also, reworked the L1 cache init code to match the e500mc L2 init code that first invalidates the cache and locks. Than enables the cache and makes sure its enabled before continuing.

* mpc85xx: Add eSDHC support for MPC8569E-MDS boardsAnton Vorontsov2009-10-27-0/+4
| | | | | | | | | | | | | | | | | | eSDHC is mutually exlusive with UART0 (in 4-bits mode) and I2C2 (in 1-bit mode). When eSDHC is used, we should switch u-boot console to UART1, and make the proper device-tree fixups. Because of an erratum in prototype boards it is impossible to use eSDHC without disabling UART0 (which makes it quite easy to 'brick' the board by simply issung 'setenv hwconfig esdhc', and not able to interact with U-Boot anylonger). So, but default we assume that the board is a prototype, which is a most safe assumption. There is no way to determine board revision from a register, so we use hwconfig.

* 85xx: MP Boot Page Translation updatePeter Tyser2009-10-27-31/+78
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change has 3 goals: - Have secondary cores be released into spin loops at their 'true' address in SDRAM. Previously, secondary cores were put into spin loops in the 0xfffffxxx address range which required that boot page translation was always enabled while cores were in their spin loops. - Allow the TLB window that the primary core uses to access the secondary cores boot page to be placed at any address. Previously, a TLB window at 0xfffff000 was always used to access the seconary cores' boot page. This TLB address requirement overlapped with other peripherals on some boards (eg XPedite5370). By default, the boot page TLB will still use the 0xfffffxxx address range, but this can be overridden on a board-by-board basis by defining a custom CONFIG_BPTR_VIRT_ADDR. Note that the TLB used to map the boot page remains in use while U-Boot executes. Previously it was only temporarily used, then restored to its initial value. - Allow Boot Page Translation to be disabled on bootup. Previously, Boot Page Translation was always left enabled after secondary cores were brought out of reset. This caused the 0xfffffxxx address range to somewhat "magically" be translated to an address in SDRAM. Some boards may not want this oddity in their memory map, so defining CONFIG_MPC8xxx_DISABLE_BPTR will turn off Boot Page Translation after the secondary cores are initialized. These changes are only applicable to 85xx boards with CONFIG_MP defined. Signed-off-by: Peter Tyser <ptyser@xes-inc.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* 85xx: Ensure BSS segment isn't linked at address 0Peter Tyser2009-10-08-0/+11
| | | | | | | | | | | | | | | | When U-Boot is relocated from flash to RAM pointers are modified accordingly. However, pointers initialzed with NULL values should not be modified so that they maintain their intended NULL value. If the BSS segment is linked at address 0 its address will not be updated as necessary during relocation. This is a temporary workaround. The end goal is to add support to U-Boot to dynamically locate the BSS at an arbitrary address at runtime. When the ability to fixup the BSS inteligently is added, this workaround can be removed and the 85xx link script can put the BSS at a fixed address at link time.

* ppc/85xx: add boot from NAND/eSDHC/eSPI supportMingkai Hu2009-09-15-1/+181
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The MPC8536E is capable of booting form NAND/eSDHC/eSPI, this patch implements these three bootup methods in a unified way - all of these use the general cpu/mpc85xx/start.S, and load the main image to L2SRAM which lets us use the SPD to initialize the SDRAM. For all three bootup methods, the bootup process can be divided into two stages: the first stage will initialize the corresponding controller, configure the L2SRAM, then copy the second stage image to L2SRAM and jump to it. The second stage image is just like the general U-Boot image to configure all the hardware and boot up to U-Boot command line. When boot from NAND, the eLBC controller will first load the first stage image to internal 4K RAM buffer because it's also stored on the NAND flash. The first stage image, also call 4K NAND loader, will initialize the L2SRAM, load the second stage image to L2SRAM and jump to it. The 4K NAND loader's code comes from the corresponding nand_spl directory, along with the code twisted by CONFIG_NAND_SPL. When boot from eSDHC/eSPI, there's no such a first stage image because the CPU ROM code does the same work. It will initialize the L2SRAM according to the config addr/word pairs on the fixed address and initialize the eSDHC/eSPI controller, then load the second stage image to L2SRAM and jump to it. The macro CONFIG_SYS_RAMBOOT is used to control the code to produce the second stage image for all different bootup methods. It's set in the board config file when one of the bootup methods above is selected. Signed-off-by: Mingkai Hu <Mingkai.hu@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
